The Write
provides facilities for writing random sized cells. Users can configure minimum and maximum
sized portions of a cell. The portions users can configure are the row, column family, column qualifier and value. Note that the sizes are uniformly
distributed between the minimum and maximum values. See WriteOptions
for available options and default sizing
information.
The Scan provides users with the ability to query tables generated by the Write. It will pick a tablet at random and scan the entire range. The
amount of times this process is done is user configurable. By default, it happens 1,024 times. Users can also specify whether or not the scan should be
isolated or not.
There is no shared state intended by either of these services. This allows multiple clients to be run in parallel, either on the same host or distributed
across hosts.Copyright © 2011–2015 The Apache Software Foundation. All rights reserved.
